• Improving salinity tolerance in crop plants: a biotechnological view (2008, background): “The differences in the expression levels of AtNHX1 or AtAVP1 may affect the potential to sequester Na+ in vacuoles of the leaves.”

• Regulation of ion homeostasis under salt stress. (2003, background): “Overexpression of the Arabidopsis Hþ-pyrophosphatase, AVP1, was shown to improve salt as well as drought tolerance [24].”
• Co-expression of the Suaeda salsa SsNHX1 and Arabidopsis AVP1 confer greater salt tolerance to transgenic rice than the single SsNHX1 (2006, background): “4A, 5A) (this result was similar to that of Zhang et al. (2001) and Gaxiola et al. (2001) ), which might result from ion homeostasis due to the expression of SsNHX1 and AVP1.”
• Overexpression of a plasma membrane Na+/H+ antiporter gene improves salt tolerance in Arabidopsis thaliana (2003, background): “thaliana vacuolar Na + /H + antiporter AtNHX1 or the vacuolar H + -pyrophosphatase AVP1 was reported to confer salt tolerance on transgenic plant”
• Physiology and molecular biology of stress tolerance in plants (2006, background): “Nevertheless, an overexpression of the AVP1 gene encoding the native vacuolar H+-translocating pyrophosphatase resulted in an increased salinity tolerance in Arabidopsis compared with the wild-type plants (Gaxiola et al., 2001).”
• Mechanisms of salinity tolerance. (2008, background): “Increased salinity tolerance of a range of plant species overexpressing NHX genes (5, 11, 15, 59, 138, 143, 144) or AtAVP1 (45) indicates the feasibility of such a mechanism and suggests that this process is important for Na+ tolerance not only in Arabidopsis but also across plant species.”

• Transgenic Plants for Abiotic Stress Resistance (2010, background): “…for tonoplast transport of solutes into vacuoles include the overexpression of the Arabidopsis H+-pyrophosphatase (H+-PPase; AVP1) in Arabidopsis (Gaxiola et al. 2001), upregulation of AVP1 in tomato (Park et al. 2005c), heterologous expression of the Thellungiella halophila vacuolar-H+-PPase…”

• Vacuolar transporters and their essential role in plant metabolism. (2006, background): “…V-PPase is heat stable, and exhibits a temperature optimum of ;50 C. Overexpressing the vacuolar H+-PPase AVP1 in Arabidopsis thaliana resulted in plants exhibiting a higher salt tolerance, which was probably a consequence of an increased proton gradient across the tonoplast (Gaxiola et al., 2001).”
